Features: V/F control, vector control and output torsion control. Built-in communication interface RS-485. With speed potentiometer and external panel. Built-in synchronous control and proportional synchronization control. 6 speed control modes, can work automatically. It can select multiple running commands or frequency channel. You can get some or all of the keys locked (unlocking the analog potentiometer). The normally open relay and two high-configuration outputs have 100 types of optional methods. 5 digital optoisolated inputs, 100 types of optional methods. 1 analog input, 2 analog output channels. Having the function of textile pendulum frequency, it can be widely used in textile equipment. Built-in timer/counter defined by the user. At zero speed, it can output 0-100% adjustable torsion, with zero speed braking function.
